The LT-400CL is a prism-based colour line scan cameras
built around a series of three custom-designed CMOS linear
sensors.

Key features
It features three, high-performance CMOS, prism-mounted sensors,
each with 4096 (4K) pixels. outputting 4K line resolution at 16,180 lines
per second while maintaining image quality at a signal-to-noise ratio
of 55 dB or higher.

The single optical plane of the prism-based design eliminates
off-angle viewing problems, complicated alignments, and other
issues that often create issues with tri-linear camera alternatives.

Typical of JAI’s multi-imager colour cameras, the dichroic coatings
on the prism boundaries provide steep spectral curves
which minimize colour “crosstalk” and so provide superior
colour precision compared with tri-linear or dual-line colour
solutions. These hard dichroic coatings also don’t suffer the degradation
of the soft polymer dye filters on the other types of sensors consequently
giving accurate color performance over a longer product life span.

Application
The sub-pixel sensor alignment delivers precise colour values for each
pixel, making the camera ideal for web-based inspections
where accurate color information is required.
